This has been a challenge for me. With countless favorites, I'm left with only 3 true hall of fame entries. Those where the band seemed to be just as amazed as those who witnessed what happened. (I was at one of these shows, in the heyday of my college years, and will never forget what that room felt like when the lights went up after the second set at MSG.) Each of these performances marks a moment where the band never sounded the same thereafter imo.

In no particular order:
1) Bethel sound check "Waves" 2011
2) McNichols "Ghost" 1997
3) MSG "Mikes" 1995
